The use of coal as the primary fossil fuels in Indonesia are increasingly widespread. Now, the use of coal is not only used for the power plant but also a wide range of industries. Resulting from the use of coal bottom ash which can still be used because they save the calorific value for alternative fuel that is becoming briquette product. Through research it is known that the bottom ash can be processed into briquettes products with the addition of teak leaves charcoal to improve its quality.This study was conducted with a variety of compositions between bottom ash and teak leaves charcoal. The treatment uses ratio of coal bottom ash : teak leaves charcoal 0%:100%, 20%:80%, 40%:60%, 50%:50%, 60%:40%, 80%:20% and 100%:0%. The results showed that the optimum variation of briquettes is a variation of 20 % coal bottom ash and 80% teak leaves charcoal, this briquettes has a water content of 4,052 %,ash content of 36,358 %, calorific value of 4.520 cal/g, compressive stength of 2,383 kg/cm2,CO 54 ppm or 61,84 mg/Nm3,Cu 0,85 µg/g and Zn 1,21 µg/g.The result of the briquttes characteristics test showed that with increasing amounts of teak leaves charcoal can increase the moisture content and calorific value, and be able to lower ash content and compressive strength.
